Thus schemes that can differentiate network states more precisely are needed in hybrid wired-wireless networks to improve performance of TCP protocols
Despite increased TCP-based WMN services emerge, the TCP protocol
itself has poor performance in WMNs [1-2].
In MANET, data transmission failures due to the environment (like mobility, collisions, etc) lead often to the congestion control activation by TCP protocol
then the number of packets is reduced.
These transport protocols carry out a connection, but the main difference between them is that TCP protocol
is connection oriented protocol with logical connection, while UDP--connectionless and establishing a connection before sending data is not necessary.
Communication with scales/sensors with TCP protocol
can be found at the transport layer of OSI model and is responsible for ensuring the correct transmission of data between two end points in the IP network ( IP does not guarantee the correct transmission ).
The same way data applications use the TCP protocol
to satisfy their requirements, voice and video streams use a protocol called RTP (real time protocol) (ran sported on UDP (user datagram protocol).
Several contributions are proposed to address TCP protocol
issues with wireless links.
The SM500F's built-in Ethernet communications link enables historical data to be remotely downloaded while this link also provides the ability to interface with a SCADA system using Modbus TCP protocol
as well as sending email notifications of process status and events.
In this paper, we propose a new TCP protocol
called TCP for cognitive radio (TCP-CR) for CRNs.
1-(a), traditional TCP protocol
adopts a reactive approach to cope with packet losses.
